Pomacea columellaris is a South American species of freshwater snail in the apple snail family, Ampullariidae . [2]
Pomacea columellaris was originally described as Ampullaria columellaris by Augustus Addison Gould in 1848, based on a holotype shell collected during the United States Exploring Expedition from 1838-1842. [3] They were named for their notable columella, comparable to those of Helix land snails. [4] In 1904, Dall proposed a section or subgenus of Ampullaria (later treated as synonymous with Pomacea ) called Limnopomus , [5] with A. columellaris as the type species. [6] After 1991, Limnopomus was also considered synonymous with Pomacea. [7] [8]
The species has a heavy, oval shell with a sharp spire. [9] Its operculum is corneous and able to retract inside the shell's aperture. [9] [10] They lack an umbilicus [4] and are often yellow in color. [10]
P. columellaris is found in rivers in the highlands of Venezuela, Colombia, Ecuador (Pastaza Province), [11] and Peru. [5]
Ampullariidae, whose members are commonly known as apple snails, is a family of large freshwater snails that includes the mystery snail species. They are aquatic gastropod mollusks with a gill and an operculum. These snails simultaneously have a gill and a lung as functional respiratory structures, which are separated by a division of the mantle cavity. This adaptation allows these animals to be amphibious. Species in this family are considered gonochoristic, meaning that each individual organism is either male or female.
Pila is a genus of large freshwater snails with an operculum, African and Asian apple snails, aquatic gastropod mollusks in the family Ampullariidae, the apple snails.
Pomacea is a genus of freshwater snails with gills and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. The genus is native to the Americas; most species in this genus are restricted to South America.
Pomacea canaliculata, commonly known as the golden apple snail or the channeled apple snail, is a species of large freshwater snail with gills and an operculum, an aquatic gastropod mollusc in the family Ampullariidae, the apple snails. South American in origin, this species is considered to be in the top 100 of the "World's Worst Invasive Alien Species". It is also ranked as the 40th worst alien species in Europe and the worst alien species of gastropod in Europe.

Pomacea scalaris is a species of freshwater snail of the Ampullariidae family. It was described by Alcide d'Orbigny in 1835. It is found in Bolivia, Paraguay, Argentina, Brasil, and Uruguay. It is invasive in Taiwan. First documented in 1989, it was possibly introduced alongside Pomacea canaliculata illegally brought to the country for aquaculture.

Pomacea auriformis is a species of freshwater snail in the family Ampullariidae, described by Lovell Augustus Reeve in 1856 as Ampullaria auriformis. Its distribution is along the Caribbean coast of Central America. There has been debate over whether this species may be a subspecies of Ampullaria hopetonensis.
